HolsTlNe APPARATUS FOR iiti-zvAToas, atc.

SPECIFICATION forming part of Letters Patent No. 232,338, dated September 21, 1880.

Application filed August 6, 1880.

To all whom it may concern:

Beit known that VI, NicHoLs B. OUsHiNe, of Jersey City, in the countyT ot' Hudson and State of New Jersey, have invented certain Improvements in Hoisting Apparatus for Elevators, Ste., of which the following is a speciication.

-This invention relates to that class of apparatus commonly termed hoisters,7 and more particularly designed for workin g the elevators on docks, in warehouses, and other places; and its object is to enable the apparatus to be adjusted to the particular location in which it is to 'ne placed and used, so that it maybe set up complete at the manufactory, instead ot' requiring tobe taken more or less in piecemeal to the place where it is to be permanently located,and there specially and iixedly arranged for use. This special adjustment and arrangement ordinari] y occurs, for the reason that the direction ot' the driving-belts ot' the apparatus is commonly arbitrarily determined by the shape and sizeof the space orroom in which the apparatus is to be placed-in other words, by the eXigencies of each particular case.

Myinvention comprises a novel construction or combination of parts, whereby the apparatus as a whole may be completed and set up ready for use, but capable of adjustment to bring its parts in such relation with each other that the belt may be run in any direction radially from the axis of the driving-pulleywithout taking apart the machine, and without any other manipulation than the turning ot' certain portions of the apparatus around ajoint provided to permit of the adjustment aforesaid.

Figure 1 is a side elevation, Fig. 2 a plan view, and Fig. 3 an end view, of an apparatus embracing1 my said invention.

A is the supporting-iframe of the apparatus, which may be of any suitable or appropriate character, but which, as represented in the drawings, is designed to be bolted to the ceiling of the room in. which the apparatus is placedforoperation. This framecarriesorsupports the winding-drum B and the intermediate or counter shaft, C, which has at one end a pinion, a, which gears into the spur-wheel b of the winding-drum, and at the other end a spur-wheel, c, which gears into a pinion, d, on the pulley-shaft D, the said pulley-shaft D (No model.)

having what, for our present purpose, may be termed the operatin g-pulley, C, which is fast i shaft D of` the operating-pulley C, so that in whichever direction the frame G maybe turned it will still be radial to the shaft D-in other words, to the axis ot' motion ot' the operatingpulley U. Upon the outer end ot' this frame G is placed the belt-shipping mechanism, which may be of any ordinary or suitable kind, but which, as represented in the drawings, comprises the shi pping-levers g, (said levers being represented in 3,) which are pivoted upon suitable bearings h, provided on the cross-piece f, as represented in Fig. 2, the requisite lateral movement ot' the said shipping-levers g being given by studs i, provided on a'transverselymovable rod, H, one end of which slides in a bea-ring formed in one of the outwardly-projectinglugs or portions la ofthe t'rame G, and the aforesaid studs i fitting into the slotted short arms a ofthe shipping-levers g.

The requisite longitudinal movement is given to the rod H by means ot' a nut, fm, on

ktheinner end thereof, into which works the spiral thread a of the screw I, which latter is supported in a bearing in one of the lugs or portions lc of the frame G, as more fully represented in Fig. 2, the said screw I being attached to a pulley, K, which is intended to be actuated by the usual vertical belt used in passenger and other elevators for controllin g the movement of the elevator-car. The same longitudinal movement which thus actuates the belts to throw one or the other from or to the operatingpulley O serves also to give movement to thebrake L withreference to said pulley G. The brake L is secured to brake-bar N, which at one end is pivoted to the frame G, as shown at r, the Vopposite'end being connected by a link, M, at one end of the-rod H, but opposite that at which the pulley K is placed, so that when the rod H approaches the extreme limit of its movement in either direction the brake L will be withdrawn away from the operating-pulley C, at which time the said pulley C is under operation by a belt running thereon, whereas when the rod H is brought to the position .in which the belts are brought upon the loose pulleys E F the brake L is applied to the face ofthe pulley C.

It will be observed that in practice it is -especially desirable, or even necessary, that the belt-shipping and brake-actuating mechanism should' be constituted between the two opposite portions of the belts which run upon the pulleysE C F, and it is this requirement which necessitates a difference of position as concerns said parts, according to the exigencies of any particular case. Now, therefore, inasmuch as the said belt-shipping and brake-actuating mechanism-one or both, but especially the latter-is carried upon the outer portion of the frame G, which, at its inner portion, is pivoted upon the shaft D of the operatingpulley C, the adjustment of the frame G, as hereinbefore explained, will bring the aforesaid belt-shipping and brake-actuating mech- ,anism into a position radial to the axis of the pulley C, so that the said mechanism may be adjusted to act in proper relation with the belts, no matterin what direction the said belts may run from the pulley C and its adjoining loose pulleys E F, so that the machine made complete and set up for operation at the manufactory may be put in any place, regardless of the necessary direction of the driving-belts, and adjusted to said direction of the driving belts by simply turning the frame Gr around its axis of movement or adjustment-namely, the shaft D-and fixing it in such position to hold the belt-shipping and brake-actuating mechanism stationary. In order to thus re tain the frame Gr in the position in which it is l adjusted the portions U of the main frame A,

in which are formed the bearings of the shaft D, have curved slots concentric with the axis of said shaft, through which are passed bolts a, the said bolts extending through the said slots from the side pieces, e, of the frame G, and having at their outer end nuts b', which tighten against the outer surfaces of the parts U of the main frame A, so that the side pieces, e, are griped in frictional contact to the parts U of the frame A with such tenacity as to retain the said frame in position, as hereinbefore explained. I

It is to be understood that the relative arrangement of the drum B and' the operatingpulley C, with their intermediate gearing, may be changed or modied to any extent, and that in like manner the construction and arrangement of the belt-shippin g and brake-actuating mechanism may also be changed and modified Without affecting the lprinciple of my invention so long as the said belt-shipping or brakeactuating mechanism-one or bothis provided upon the outer end of the frame G, and the latter frame Gr has its axis of movement or adjustment substantially coincident with the axis of motion of the pulley C.

It is also to be observed that the said frame G, instead of being pivoted direct upon the shaft D, may be pivoted upon bearings formed upon the main frame A, the arrangement of the pivots themselves being immaterial so long as the axis of movement or adjustment of the frame is substantially coincident to the axis of motion of the pulley C.

What I claim as my invention is- In a hoisting apparatus for elevators, 86o., the combination of the adjustable frame G, provided with mechanism for controlling the operating-pulley C, with the said operating-pulley and the winding-drinn actuated thereby, the aforesaid frame Gr being adjustable around an axis substantially coincident with that ol' the operating-pulley aforesaid, all substantially as and for the purpose herein set forth.
